Business model statements

After you define the business model, you can add statements for its entities, events, and attributes. In the Statements editor, you write behaviors for your business model definitions.

Entity initialization from an event
You can initialize entities when you need them, at the reception of a first event that references these entities. Use the business rule language in the business model statements tab to declare the initialization of an entity from an event.
Enriched attributes
In the business model statements, you can use external data to enrich entity attributes that you defined in the business model.
Derived attributes
In the business model statements, you derive the value of an attribute from the values of other attributes. You can derive attributes of entities and attributes of events.
Shared aggregates
Use shared aggregates to compute the value of an entity attribute by aggregating values from events that are associated with this entity. You can use the following aggregation operators: maximum, minimum, average, total, and number of. Shared aggregates can be more efficient than aggregates defined in rules to calculate a value from the history of past events because they can be used by multiple agents and applied to multiple time periods and time points.
